Wa - ON for the set interval triggered with the control contact S.
The input of the time relay is supplied with voltage U continuously. Closing of the control contact S does not start the interval T, and it does not change the position of the output relay R. Opening of the control contact S immediately switches on the output relay R for the set time. After the interval T has lapsed, the output relay R switches off. Opening and closing of the control contact S in the course of the interval T does not affect the function to be performed. The output relay R may be switched on again for the set interval with another closing and opening of the control contact S.
Relays performing the function "Wa": MT-W..., RPC-.MA-..., RPC-1MC-UNI, RPC-.MD-UNI, TR4N 1CO, 2CO, TR4N 4CO, PIR15...T
